摘要： With the rapid development of the city,the concept of ecological environment has been integrated into everyone’s heart.In the new era,people also have higher requirements for the quality of living environment.However,at this stage,with the development of urbanization and industrialization,the problem of environmental pollution has become more and more serious.Therefore,we must do a good job in urban environmental monitoring,pay attention to the protection of urban environment,design and implement effective governance methods,so as to improve the quality of environmental governance.This article analyzes the problems in urban environmental monitoring,and formulates reasonable treatment methods and suggestions.

摘要： Background: Human Immuno-Deficiency Virus Self-Testing (HIVST) is a process where an individual who wants to know their HIV status collects a specimen, performs a test and interprets the result by themselves. HIVST data from the Zimbabwe AIDS and TB Program (ATP) directorate showed that between 2019-2020, only 31% of the target HIVST kits were distributed in the country. Mashonaland West Province was one of the least performing provinces in meeting targets for HIVST kits distribution. Gaps in the implementation of the HIVST in the province ultimately affect the nationwide scaleup of targeted testing, a key enabler in achieving HIV epidemic control. We analyzed HIVST trends in Mashonaland West Province to inform HIV testing services programming. Methods: We conducted a cross-sectional study using HIVST secondary data obtained from the District Health Information Software 2 (DHIS2) electronic database. We conducted regression analysis for trends using Epi Info 7.2 and tables, bar graphs, pie charts and linear graphs were used for data presentation. Results: A total of 31,070 clients accessed HIVST kits in Mashonaland West Province from 2019-2020. A slightly higher proportion (50.4% and 51.7%) of females as compared to males accessed HIVST kits in 2019 and 2020 respectively. Overall, an increase in the trend of HIVST kits uptake was recorded (males R2 = 0.3945, p-value = 0.003 and females R2 = 0.4739, p-value = 0.001). There was generally a decline in the trend of community-based distribution of HIVST kits from the third quarter of 2019 throughout 2020 (R2 = 0.2441, p-value = 0.006). Primary distribution of HIVST kits remained the dominant method of distribution, constituting more than half of the kits distributed in both 2019 (67%) and 2020 (86%). Conclusion: Mashonaland West Province was mainly utilising facility-based distribution model for HIVST over the community-based distribution model. We recommended training more community-based distribution agents to increase community distribution of HIVST kits.

摘要： [Objectives]To analyze the occurrence rules and factors influencing adverse reactions of breviscapine for injection,explore potential drug risks,and guide the clinical rational medication.[Methods]The retrospective analysis method was used to analyze the case reports of adverse reactions of breviscapine for injection,and analyze the gender and age distribution of the cases,the patient's medication status,the adverse reactions involving organ/system damage and clinical manifestations,the occurrence time,duration,and outcome of the adverse reactions.[Results]Adverse reactions of breviscapine for injection were mainly concentrated in middle-aged and elderly patients aged 45 and above,accounting for 85.35%;in the gender distribution,females were higher than males;adverse reactions involved multiple organ/system damages.Among them,75.86%of patients had adverse reactions after the first medication,and 11.77%of reported patients had concomitant medications.[Conclusions]The adverse reactions caused by breviscapine for injection may be related to the patient's age,gender and irrational medication.

摘要： Burkina Faso conducted a community selection of the indigent in eight health districts. The selection targeted 15% to 20% indigent per district. This study analyzed the data of this selection from the databases of the Ministry of Health. Descriptive analysis and time series modeling were performed. Indigents were predominantly female, heads of household were mostly elderly, and the average age of household members ranged from 21.9 to 29.8 years. The households were small. Indigents were mostly uneducated and employed. They all belonged to a given religious denomination, Muslims were the most numerous. The majority of the indigents were married and almost a quarter of them were widows. About 2% to 17% of indigents were selected depending on the district. Forecasts showed both an increase and a decrease in the use of health care by indigents. The study recommends considering the poverty level specific to each district when selecting, strengthening education policies targeting the indigent, improving the socio-health conditions of the indigent including specific actions considering age, sex and marital status, and the formulation of an employment policy targeting the indigent. Analyzes of the relationship between poverty and religion may allow the exploitation of religious capital for the benefit of the indigent.

摘要： Acute septic arthritis in children is an orthopaedic emergency.A delay in diagnosis and inappropriate treatment can result in devastating damage to the joint with lifelong disability as a consequence.The clinical presentation can be a diagnostic challenge,especially in young children.A recent systematic review showed that joint tenderness and fever are important signals of septic arthritis.Ultrasound is helpful in detecting the presence of a joint effusion.Plain radiographs may show bone changes but magnetic resonance imaging is the most reliable imaging study for detecting concomitant osteomyelitis.The diagnosis of acute septic arthritis is highly suggestive when pus is aspirated from the joint,in case of a positive culture or a positive gram stain of the joint fluid,or if there is a white blood-cell count in the joint fluid of more than 50000/mm3.Staphylococcus aureus is the most commonly cultured organism.Recent systematic reviews have identified the most effective drainage techniques,including needle aspiration,arthroscopy and arthrotomy,depending on the affected joint.After the drainage procedure it is important to monitor the clinical and laboratory outcomes.Additional drainage procedures may be necessary in select cases.

摘要： In high voltage networks for the transport of electrical energy, lightning, a phenomenon as dangerous as it is impressive, with an easily recognizable form, can affect a power line by striking either a phase conductor, a tower or a guard cable, thus causing more dangerous and constraining stresses on the lines for its proper operation. Thus, this article aims to analyze the behavior of a HV line during an atmospheric discharge and assess the spatial and temporal distribution of the lightning current wave. For this purpose, the generalities on the transmissible power in case of link without resistance and the modeling of the atmospheric surge propagation established on the basis of the theory of the lines with distributed constants implementing the wave equation known as the Alembert equation have been developed. Through this research, we are interested in the study of the space-time distribution of the lightning current wave in order to model the radiated electromagnetic field and to examine the influence of the atmospheric discharge induced overvoltage on the transportable power of a High Voltage AC Transmission line, for a good selective protection in order to illuminate the parasites. The 2D simulation based on engineering and “Transmission Line” models have been developed as well as the verification of the coherence of the different models, by comparing the fractal dimensions of the program results with those of the experimentally obtained figures.
